AUTO METER Full Sweep Electric Pressure Gauges User manual

Brand: AUTO METER

Model: Full Sweep Electric Pressure Gauges

Type: User manual

AUTO METER Full Sweep Electric Pressure Gauges provide accurate readings for fuel, oil, nitrous, and brake pressure. They feature a self-calibration function, a 2 5/8" or 2 1/16" mounting hole, and a 1" grommet-protected hole for wiring. The gauges are compatible with most vehicles, but a 3227 Line Kit and 3279 restrictor are required for 1998-2002 (some 2003) Cummins diesels. Not compatible with Nitromethane, Methanol, or 100% MTBE.

Use teflon sealing compound sparingly

where symbol indicates. (Tape not

CAUTION!

As a safety precaution, the

+12V terminal of this product

should be fused before

connecting to the 12V ignition

switch. We recommend using

a 1 Amp, 3AG fast-acting type

cartridge fuse (Littlefuse® #

312 001 or an equivalent).

Installation - Nitrous Pressure

1. Check that you have all parts required for installation, and the

engine is cool.

2. Disconnect the negative (-) battery cable.

3. Gauge mounts in a 25⁄8” hole for 25⁄8” gauges, and a 21⁄16” hole

for 21⁄16” gauges. Use supplied brackets and nuts to secure

gauge to dash.

4. Drill 1” diameter hole where wires pass through sheet metal

(such as firewall) and install rubber grommet provided.

5. Connect the white wire to dash lighting or switchable 12v light

source, the red wire to switched +12V source and the black wire

to ground. (see diagram for details)

6. Make sure the nitrous bottle valve is closed and there is no

pressure in the system.

7. Remove the main nitrous feed line from the bottle or the nitrous

solenoid. Install the in-line gauge adapter (e.g. NOS part #16770

or #16771) either on the nitrous bottle or nitrous solenoid. Re-

install the main nitrous feed line. Install pressure sender and

wiring harness. For mounting off bottle in rear of car, use 20’

sender harness model 5223.

8. Open the nitrous bottle valve.

NOTE: Test all fittings and hoses for any leakage. If any leaks

are detected, determine the cause of the leak and

repair. Do not operate vehicle if any leaks are detected.

Installation - Fuel & Oil Pressure

1. Check that you have all parts required for installation, and the

engine is cool.

2. Disconnect the negative (-) battery cable.

3. Gauge mounts in a 25⁄8” hole for 25⁄8” gauges, and a 21⁄16” hole

for 21⁄16” gauges. Use supplied brackets and nuts to secure

gauge to dash.

4. Drill 1” diameter hole where wires pass through sheet metal

(such as firewall) and install rubber grommet provided.

(Grommet will require slit.)

5. Connect the white wire to dash lighting or switchable 12v light source,

the red wire to switched +12V source and the black wire to ground.

(see diagram for details)

CAUTION: If you will be working with the fuel system, take care to

insure no sparks or flames occur. Do not smoke while installing the

fuel pressure sender.

WARNING: The fuel system is pressurized and often retains this

pressure for an extended period of time. Properly vent

your fuel system before installing the fuel pressure sender.

If you are not familiar with the proper method of venting,

you MUST have this done by an experienced mechanic.

NOTE: When the ignition is off the pointer may not always

rest at zero.

WARNING: Not compatible with Nitromethane, Methanol,

or 100% MTBE.

6. [For oil pressure gauge installation, an optional 1⁄4” NPT adapter

is included. For fuel pressure gauge, install the 1⁄8” NPT pressure

sender into the fuel system (See caution below). For Ford fuel injected

applications with a Schrader valve in the fuel rail, use adapter 3280

between the fuel rail and pressure sender.]

If unit is to be installed on a high vibration application such as a full race

engine or engine capable of high RPM, it is strongly recommended that

the sender be remote mounted to either the fenderwell or firewall, to

insulate from vibration. Failure to remote-locate pressure senders

on such an application could result in gauge failure and potential

damage to vehicle and/or operator injury. Braided stainless steel lines

are sold separately by Auto Meter, and can be used to accomplish this.

8. Reconnect negative (-) battery cable.

NOTE: Test all fittings and hoses for any leakage. If any leaks are

detected, determine the cause of the leak and repair. Do not

operate vehicle if any leaks are detected.

ATTENTION DODGE DIESEL OWNERS: If using on ‘98-’02 (some

‘03) Cummins diesels, you MUST use #3227 Line Kit and #3279

restrictor to prevent premature failure of sender. Failure to do so will

void warranty.

Power-Up

The pointer will move backward to the stop pin and then move to the zero box. This procedure is an auto-calibration

function and is performed on every power-up. While this test is being performed, the gauge may make a clicking

sound. This is normal.

1. Check that you have all parts required for installation, and the

engine is cool.

2. Disconnect the negative (-) battery cable.

3. Gauge mounts in a 25⁄8” hole for 25⁄8” gauges, and a 21⁄16”

hole for 21⁄16” gauges. Use supplied brackets and nuts to

secure gauge to dash.

4. Drill 1” diameter hole where wires pass through sheet metal

(such as firewall) and install rubber grommet provided.

5. Connect the white wire to dash lighting or switchable 12V light

source, the red wire to switched +12V source and the black

wire to ground. (see diagram for details)

6. If you are not familiar with proper brake system bleeding

procedures, do not install this gauge. Have a qualified

mechanic do it for you.

7. Locate a 1⁄8”-27 NPT port in your brake system in a location

where you would like to measure brake pressure. If no port is

available, you will need to install a tee fitting in the brake line

you want to measure. Only use fittings that are approved for

use in brake systems.

8. Install the pressure sensor in the 1⁄8”-27 NPT port using a

Teflon thread sealing compound.

9. Bleed the brake system using standard brake bleeding

procedures.

Again, if you are not familiar with proper brake system

bleeding procedures, do not install this gauge. Have a

qualified mechanic do it for you.

Note: Install sensor with electrical connector

facing down to allow any air in the sensor

to escape during bleeding.
